First, SUPER THANK YOU to everyone how gave my some feedback. It is so appreciated.
Yesterday, my husband was really worried about the FC level. He made a fine powder from 250g of Vitamin C (100% ascorbic acid with absolutely nothing else) and drop that powder slowly in the skimmer. We did nothing else to the pool. The pump is still on max speed and running 24/7.
This morning the green color is almost all gone, the water is clear and the water temp is at 46F. I did the FC test in the following manner: 5ml of pool water with 1 heaping scoop of DPD powder = turned bright pink, then added 15 drops of R-0871 and it became a very light pink = FC??? I do not know which way to multiply. I continued on adding a few drops but the light pink does not budge. Should it turn completely clear? Why is it staying slightly pink? Adding 5 drops of R-0003 did nothing to the color so CC=0. - As I wrote this post (15-20 minutes), the solution is getting brighter, more pink. I did not through it out yet, it is still on the counter. Is this normal? Could we have an issue with one of the chemicals involved in the testing?
I have checked our well analysis of the last 3 years, and we never had an issue with high levels of copper in our well. We are in for another cold cloudy day. Every day the weather forecast pushed back the warmth and sun.
What do we do now?
1) Slamming: are we done? do I go back to the check list for the slamming process?
2) Copper: I am thinking of paying for a lab analysis of the pool water at the same lab we get our well water tested every year. I have read the suggested threads on copper. The only solution is to change the pool water. Other than potential stains from the copper any danger to the pool equipment? Can it damage our new heat pump? It has titanium coils. I am wondering if we can live with this for this summer and lower the level before the winter, empty further next spring and fill with brand new water. If we change the water this year, I have to wait until the FC level is back to zero, we empty directly in a forest.
